The client for Puck

This is a client for sending data to Puck over a websocket. It integrates with your applications Redux store and React components to provide a clean way to send custom metrics. Additionally, it standardizes and automatically injects data that is useful across any event. Checkout the Puck data model to see what that looks like.


$ npm install @dosomething/puck-client

Usage with React

Add the Puck Provider to your React+Redux application.

import React from 'react';
import { Provider } from 'react-redux';
import { PuckProvider } from '@dosomething/puck-client';
import initializeStore from './initializeStore';
import historyInit from './historyInit';

const App = () => (
  const store = initializeStore();
  const history = historyInit();

  const getUser = () => (
  const isAuthenticated = () => (

  return (
    <Provider store={store}>
        {/* ... */}

export default App;

Next, connect your components to Puck using the PuckConnector.

import { connect } from 'react-redux';
import { PuckConnector } from '@dosomething/puck-client';
import Feed from './Feed';
import { clickedViewMore } from '../../actions';

const mapStateToProps = state => ({
  campaignId: state.campaign.legacyCampaignId,

const actionCreators = {

export default connect(mapStateToProps, actionCreators)(PuckConnector(Feed));

From here you can either wrap a Redux action with trackEvent,

const mapPropsToEvents = trackEvent => ({
  clickedViewMore: props => (
    trackEvent('feed clicked view more', { campaignId: props.campaignId })

export default connect(mapStateToProps, actionCreators)(PuckConnector(Feed, mapPropsToEvents));

Or you can manually decide when to call trackEvent by using the function the props.

import React from 'react';

const Feed = ({ trackEvent, campaignId }) => {
  trackEvent('feed render', { campaignId });

  return (
    <div className="feed" />

export default Feed;

Usage without React

When using Puck without React, add the Puck Engine to your app.

import { Engine } from '@dosomething/puck-client';

let puck = null;

function onReady() {
  puck = new Engine({
    source: "your-app-name",
    puckUrl: window.env.PUCK_URL,
    getUser: () => window.state.userId,

function onClick() {
  puck.trackEvent('on click', { button: true });

All of the same params from the React version can be used here, but some have been intentionally omitted (eg: history) because they are irrelevant for non-React Router based applications.

When using the pure Puck engine, simply call trackEvent on it.

React Waypoints

Use Waypoints to track when users scroll past a certain point.

import { PuckWaypoint } from '@dosomething/puck-client';

const Example = () => (
  <div className="container" style={{ height: '1000px' }}>
    <PuckWaypoint name="half-way-point" />

Available props: name: Required. Name of the waypoint. onlyOnce: Optional (Defaults true). Waypoint only emits an event one time. waypointData: Optional (Defaults null). Additional data to track on the waypoint event.

Error Handling (Optional)

The PuckProvider and Engine both accept an onError parameter function, which will be invoked whenever the internally utilized socket emits a 'connect-error' or 'error' event.
